What are transformers?

A transformer, also known as a "trafo," is used to increase or decrease an alternating current. This allows the electrical circuits to be galvanically separated, meaning they are isolated from each other as electrochemical power sources.

What is an electronic halogen transformer?

Electronic halogen transformers for lighting sold by ET48 convert the mains voltage of 220 volts to the safe 12 volts low voltage. This type of transformer is therefore intended exclusively for halogen lamps that operate at this low voltage. Because of this lower voltage, these lamps can be used in, for example, the so-called 'wet areas' (shower, bath, is also called zone 1) of bathrooms or used for ceiling spotlights. In these cases, the transformer is concealed above the ceiling.

The size and power of the halogen transformer depends on the wattage and number of halogen lamps that can be connected. That is why there are various shapes and models of transformers which can all be found in our webshop!

CAUTION: not suitable for dimmable 12V LED lamps

Halogen transformers are NOT suitable for dimmable 12V bulbs. The bulbs will flicker, are poorly dimmable and will break down quickly. LED lamps require much less power than halogen lamps. If you switch to energy-efficient 12V dimmable LED lamps, it is very wise and also necessary to replace the transformer with a so-called dimmable LED driver. These are suitable for dimming LED lamps. You can find dimmable LED drivers on this page.
